Sheath a concrete wall detail.

Zip system wall sheathing and tape has been rated 1 in quality every year since 2015 in builder magazine s annual brand use studies. The sheathing offers some additional r value and it s a continuous insulation layer outside of the framing. Sheathing typically plywood or osb. The irc and ibc provide prescriptive framed shear wall designs that may be incorporated into the building design to resist lateral loads.

This differs from figures 2 12 in that above grade wood frame wall is constructed of 2x6 framing which overhangs the foundation wall. From a comfort standpoint here in climate zone 4 we think this will be a good tradeoff to using 2 6 walls that have a moderately higher r value but a bit more thermal bridging. Structural exterior wall sheathing ties framing studs together making the walls resistant to twisting and bending. It consists of a concrete masonry cmu foundation wall with exterior insulation.

Nearly all homes have exterior shear walls. The asphalt felt paper should go over the sheathing wrap which should also wrap the corners at least 6 in. Exterior wall on slab must be out on the edge. Exterior wall sheathing is either structural or non structural.

This prevents water from leaking under the bottom of the wall to the inside of the building. Inside corners also benefit from a spline see illustration. For multi story buildings the sheathing on the bottom should extend down to the bottom of the lowest framing member extend to the halfway point on rim joist as shown in red.

An exterior wall must be placed on the outside edge of the slab so the exterior siding laps down and over the edge of the slab. A simple approach that works well is to add a spline of asphalt felt paper at outside corners that extends 6 in. Over the years variations of this system have been developed. The dryvit system consisted of expanded polystyrene bead board attached adhesively to the sheathing and covered with a lamina composed of a modified cement base coat with woven glass fiber reinforcement and a textured colored finish coat.

The prescriptive designs specify requirements for wall bracing braced wall lines and braced wall panels. Consider a wood shed floor treated lumber joists and plywood.
